Abstract :
[en] This paper describes a robust and efficient method to
obtain the steady-state, nonlinear behaviour of large arrays of electrically
actuated micromembranes vibrating in a fluid. The nonlinear electromechanical
behavior and the multiple vibration harmonics it creates are fully taken into
account thanks to a multiharmonic finite element formulation, generated
automatically using symbolic calculation. A domain decomposition
method allows to consider large arrays of micromembranes by efficiently
distributing the computational cost on parallel computers. Two- and
three- dimensional examples highlight the main properties of the proposed
method.
